ALFRED E. ANDER/SEN, 0F ROCK SPRINGS, WYOMING.

Application led March 17, 1923. Serial No. 625.829.

To all whom t may concern.'

Be it known that I, ALFRED R. ANDERSEN,

a citizen of the United States, residing at Rock Springs, in the countyof Sweetwater 5 and State of Wyoming, have invented oertain new anduseful Improvements in Car Brakes, of which the following is aspecification, reference being had to the accompanying drawings.

This invention relates to certain improvements in car brakes and hasrelation more particularly to a brake of this general characterespecially designed and adapted for i use in connection with mine orkindred cars and it is an object of the invention to provide a brakehaving novel and improved .means whereby, when the same is applied, thecar may have desired travel down an inclined trackway without the use ofsprags i 20 or the like.

Another object of the invention is to provide a noveland improved brakewhich is adapted to coact with the wheels of a car at one side thereofandthe associated rail of a trackway and in a manner whereby said wheelsare raised 'out of contact with said rail so that the brake hassullicient frictional contact with the rail to properly retard thetravel of the car and especially down an inoline.`

The invention consists in the details of construction and in thecombination and arrangement of the several parts of my improved carbrake whereby certain important advantages are attained and the devicerendered simpler, less expensive and otherwise more convenient andadvantageous for use, as will be hereinafter fully set forth.

The nor-tl features of my invention will hereinafter be definitelyclaimed.

In order that my, invention may ybe the better understood,l will nowproceed to describe the same with reference to the accompantingdrawings, wherein Y Figure 1 is an elevational view of a brakeconstructed in accordance with an embodiment of my invention and inapplied posi-k tion, the associated carfbeing illustrated in Figurejl atransverse .sectional view CAR BRAKE.

taken through the upper portion of my improved brake as hereindisclosed;

Figure 5 is a view similar to Figure 1 but illustrating a brakeconstructed in accordance with a further embodiment of my invention;

Figure 6 is a view in top plan of the structure as illustrated in Figure5; A

Figure 7 is a sectional view taken substantially on the line 7 7 ofFigure 5;

Figure 8 is a transverse sectional view taken through the upper portionof the brake as illustrated in Figure 5. y

As disclosed in Figures 1 to 4 inclusive, my improved brake denotes aplate 1 of re quisite dimensions and which has its side and top marginalportions delined by the outstanding flanges 2, the side flanges 2 beingeach provided at a desired point thereon with the holding teeth 3 for apurpose to be hereinafter more p'articularly referred to.

Carried by the lower portion of the plate 1 and extending entirelythereacross is a shoe 4 adapted, when thebrake is in applied position,to have direct contact with the' rail R. The lower portion of each ofthe flanges 2 is provided with a slot 5 through which extends an endportion of a bar 6. The central portion of the bar 6 is provided with anupstanding arm 7 freely disposed through the guides 8 and 9 suitablysecured to a face of the plate 1. The arm 7 is also freely disposedthrough the upper lange 2.

The opposite marginal portions of the arm 7 are toothed as at 10 andengageable with the teeth 10 of one side of the arm 7 is a gear 11rotatably supported as at 12 by the plate 1. Secured to and extendingoutwardly from the gear 11 is an operating arm 12a whereby the requisiterocking or rotary movement may be imparted to the gear 11.

My improved brake is particularly adapted for use to retard the travelof a mine car or the like down an incline. Beforethe car reaches theincline my improved brake is arranged upon the rail R between the'wheelsW at one side of the car and, the arm 12a is moved in a direction tocause the gear `11 to impart upward movement to the arm 7. As the arm 7moves upwardly the extremities of the bar 6 engage the treads of thewheels W from below and at. the same time the shoe 4t is forced intolirmcontactwith the rail R. The'arm 7 is adapted te' be moved `The gear1p1-may be arranged at either side of the arm 7 as: preferred `and forwhich reason the opposite sides of the bar 7 are provvided with theteeth 10. .The openings 14 in Figure 1 are to provide means whereby the'gear llvvmay be readily mounted at the side of the bar 7 opposite` tothat illustrated. Iivotallyv engaged with the inner or rear face of theplate is a rock arm 15 which as lis' illustrated inFigures 1 and 2isadapted to extendandengage the rear face of anadjacent wheel W wherebythe brake in its entirety iseflectively maintained in working position.r

ffIn the embodiment of myinventioii as:A ilf lustrated in Figures 5 Ato.8 inclusive the plate lhas its side margins so formed as to snuglyengage the tread of a wheel from below as is illustrated in Figure 5,the side and-upper edges of said plate 1? being also defined by theoutstanding lianges 2a.

The shoe la is separable from the plate 1a and has its rear face.provided therealong with an outstanding flange or rib 16`which engageswithin a slot 17 produced in' the 4adjacent face of the plate. la.Bythis means the shoe la is supported for sliding movement. 'lfhe shoe4a is` also provided in its central portion with a slot .18 extendingalongthe major portion of the shoe 4a vand through which: is directedaheaded memberl 19 clarrledby therlate land whereby the S110@ 4a iseffectively maintained in applied position.

lheplowerportion .ofeach ofthe side' flanges f 2i is p'rovid'edvwithlaslot 20 through which an endv portion of the shoe 4a is adapted to-beprojected inorder toy engage a wheel W frornbelow. When the shoe lais forced into .desired engagement with 'a wheel W the side-of the plate1i and the flange 2a cari yried thereby remotel therefrom is engagedwiththe second wheel `W .whereby the desired raising of the cariefacilitated. j

The upper y:face ofthe shoe 4ta is provided a raclr 21 with'whichmeshesthe arcu- .gate rack 22c arriedby a disc23. l The disc '....23iis.rotatably supported asat .24 by the aufy 4plate le. A

lineaire nia extending. .outwafdiy from aoprafing" Qyherby therequisiterotation maylbe impartedfto .to prbject retract the shoev la,asIr'equ-ired. .The disc 23 .is'held against movement causing the arni25 to engage one of the teeth 3a suitably arranged on the side flanges2a. p

Pivotally engaged as at 2G with the rear face ofthe plate is a rock arm27 of a length to entend rearwardly of and to engage a car for traveldown an incline, a brake is 7 set by a workman upon a rail between apair of adjacent wheels W or W and an arm 12a or 25 is operated to raisesaid adjacent wheels IV or W so that the travel of the car down theincline will be retardedr by the frictional contact of thebrake upon arail and particularly by the weight of the car upon the brake resultingfrom such raising of the wheels. The brake, in practice, may be readilyapplied while the car is in motion although if preferred it canbe'brought'to a standstill at the top of the incline.

From the foregoing description. it is thought to be obvious that a carbrake constructed in accordance with my invention is particularly welladapted for use by reason of the convenience and facility with which itmay be assembled and operated, and it will also be obvious that myinvention is susceptible of some change and modification withoutVdeparting from the principles and spirit thereof and for this reason Ido not wish to be understood as limiting myself to the precisearrangement and formation of the several parts herein shown in carryingi out myinvention in practice except as hereinafter claimed.

I claim:
